Calamp

If your CalAmp device is equipped with status LEDs then please check their status. Both the green GPS and orange Communications LEDs should be solid. If the green LED is off or blinking then no valid GPS position could currently be determined and therefore no positions will be updated on the portal. If the orange LED is off or blinking then no data connectivity has been acquired and therefore no communications will occur with the portal whatsoever.

In the case of the orange Communications LED not being solid, the first step should be to confirm that the cellular data settings are correct for the SIM card being used.

In the case of the green GPS LED not being solid, it often takes several minutes for the initial GPS position to be acquired and a GPS time sync to occur.

The Calamp devices are managed remotely via a central repository, but the devices must be programmed with the APN information before they can connect to the repository. To program a terminal that is new, or changing network operators, do the following:

Connect the Calamp via a serial port at 115200 bps, 8N1

Connect via terminal software such as Hyperterm, putty, or screen

Enter the following commands:

AT$APP DEBUG ON

AT$APP PARAM 768,0,66.165.183.84

AT$APP PARAM 769,0,4763

AT$APP GPRS CONTEXT 0 "{APN}"

AT$APP PARAM 2314,0,"{APN Username}"

AT$APP PARAM 2315,0,"{APN Password}"

AT$APP GPRS CONTEXT 1 "{APN}"

AT$APP PARAM 2314,1,"{APN Username}"

AT$APP PARAM 2315,1,"{APN Password}"

AT$APP PARAM 1024,35,255,1

AT$APP PEG ACTION 70 0

The unit will now reboot. Once the terminal is restarted, enter the following command to force an immediate connection:

AT$APP PEG ACTION 49 129

The unit will now download the script from the central repository and begin reporting. This can take up to 30 minutes in poor network coverage.

The Calamp series can be connected to a VDO device which translates the fuel level with a tank profile into a sliding scale voltage of 0 to 10 volts which represents a fuel level of empty to entirely full.

To connect a single temperature sensor, connect the DATA pin of the temperature sensor which is typically white on a 4 wire model and red on a 2 wire model to the White/Blue wire on the Calamp. Then connect the GND wire which is typically black to any ground/black wire of the Calamp.

To transmit the accumulator over the air, the Accumulator Number (772, 773) must be set to the number of accumulators to transmit under Report Contents > Event Report Optional Contents > Accumulator Number in LMU Manager: Ex: 1
